The Konferenz »Lernen. Wissen. Daten. Analysen.« (LWDA) 1) is a joint conference and workshop week of several special interest groups (SIG, German FG – Fachgruppen) and working groups (WG, German: AK – Arbeitskreise) of the German Computer Science Society, addressing research in the areas of knowledge discovery, machine learning, information retrieval, database systems, knowledge management, etc.

The German acronym LWDA stands for “Learning, Knowledge, Data, Analytics”, which changed during the times:

  • Lernen – Wissen – Adaption (LWA) 2007-2015
  • Lernen, Wissensentdeckung und Adaptivität (LWA) 1999, 2004-2006
  • Lehren – Lernen – Wissen – Adaptivität (LLWA) 2003
  • Lehren – Lernen – Adaptivität (LLA) 2002
  • Lernen – Lehren – Wissen – Adaptivität (LLWA) 2000-2001

Participating Special Interest Groups (FG – Fachgruppen) and Working Groups (AK – Arbeitskreise) since 1911:

    FGs & AKs since 1999
    1999 – present
    FG-KDML (Knowledge Discovery, Data Mining and Machine Learning) (was: Machine Learning, Knowledge Discovery, Data Mining / Maschine Learning (FG-ML))
